Be' it'known thatV we, CHARLES D.

songe resident of BenvAvon, in the county of Allegheny and State ofPennsylvania,.

and ALBERT W York, county of New,York, and State of New York, haveinvented a new and useful Improvement in 'Reinforced ConcreteGonstruction and we do hereby declare the fo1- lowing to-be a full,clear, andv exact description thereof.

vOurinvention, relates to reinforced concrete construction. -7 The-.main'object of our invention is to providea'-reinforcing bar of such crosssec'- tionasftofg'ivethe maximum strength while at the-.saune timecapable of being so formed' aste-provide for interlocking said bar witha ltension vbar extending at right angles thereto, or forming amechanical bondv with the-concrete surrounding the same.

L A' further object of our invention is to provide a bar 'of thischaracter provided `with means in itself for supporting saidjaar on thecentering or making provision for the attachment thereto of tlocr orceiling strips. To these ends our invention comprises the novelvfeatures hereinafterV set forth and claimed.' 1

1u the accompanying-,drawings Figure 1 is a plan view `of al'portion' ofa lmetallic fabric used for concrete construction embodyin ourinvention; Fig. 2 is a section on the Igino 2-2 Fig. 1; Fig. 3 is anenlarged section on. the line 3 3 Fig. 1; Fig. 4 is a.

crosssection on the line 4 4- Fig. 1 Fig. 5

apperspective view of a portion of our re# hiforcedbar; Figs. 6, 7 8 9and 11 are modified forms of our invention; Fig. 10 is a cross sectionon the line 10-10 Fig. 9, and

Figu12 is a cross section on the line 12-12 Fi l1. y i f the drawingsthe numeral 2 designates a bar which may-be rolled vin suitable rolls,

said bar consisting of the'enlarged or thickbody portion 3 with theflanges 4 proectingout therefrom. The Vflanges 4 maybe slit-or cut at'-jintervals to form the loops 5 and"'where said bar is used 1nconnection with cross 'tension members 6 sa1d tension ,members7 whichmay be of the same cross Btl-EL, a resident ofk New round bar 17 passingthrough thelop 5.

be bent overthe. loops so as'fto forman inter-locking connectionat the'points -where support the bars' upon the centering while" the concreteyis being tam-pcd around the' i' fabric, the straps 1() may be cut inthe lianges ltand said straps aref'then turned down into the positionindicated-in Figs. 3 and 4. The fasteners 11 secure the 'straps to thecentering 1 2. In this manner provisionv 1s made for firmly usupportingthe fabric so that it is held in proper position when the concrete istampedin place. In addition the straps 13 may be formed in vthe flangesof the bars, said straps 'extending through the concrete 14tandforming asupport for the ceillng strips 12a which are often desirable inthis/.class of work. 0r, if desired, the strips 15 as indicated in Fig.7' may extend up through the cement and may he'attached to the strips 16to which the flooring 16 may be secured In Fig. 6 we have illustrateda-modied form of 'tension bar which consists of the Again, in Fig. 7 wehave illustrated sti another modilied form of my invention in whichinstead of forming v`a loop in the flanges, the strap 18 is formed whichis adapted to be bent up to almost entirely inclose the square tensionmember 19.

In Figs. 8 and 9 we have shown a modied form of our invention in whichthe bar 2O has its flanges 21 corrugatedpse that when the bar issurrounded' with concrete these corrugations will act as a mechanicalbond between the bar and the concrete and make a very strong and rigidconstruction.

In Figs. 11 andv 12 We have illustrated another form of our invention inwhich the 2.- In reinforced concrete construction, the combination of abar, loops formed in said bar', a tension bar passing through saidloops, said last named bar having straps formed therein adapted toengage said first named bar.

3. In reinforced concrete construction, the combination of a bar havingan enlargedor thickened body portion with flanges projecting therefrom,loops formed in said fiunzes, a tension-bnr of like cross sectionpassing` through said loops, said'last named bur having straps formed inits Ranges adhpted to engage' said first named bar.
